Wiring of the Distribution Board (Single Phase Supply From Utility Pole & Energy Meter to the Consumer Unit)

How to Wire a Distribution Board?

Distribution Board aslo known as “Panel Board”, “Switch & Fuse Board” or “Consumer Unit” is a box installed in the building containing on protective devices, such as circuit breaker, fuses, isolator, switches, RCDs and MCBs etc. The electric main supply (230V AC & 120V AC in US) is connected through secondary of the transformer (3, Phase 4 Wire System), single phase energy meter and MCBS (DP & SP) to Sub Circuits and Final Sub Circuits to protect all the connected electrical appliances and appliances through electrical wiring installation.

In the following single phase electrical wiring for home supply, We used 63A MCB (DP), 63A RCD (DP) and different rating if MCBs (SP) such as 20A, 16A, 10A etc according to your need.

In the fig below for single phase electric home supply installation and wiring of a distribution board, you may see the single phase electric supply (230V AC and 120V AC for US) service mains i.e. Line (Red) and Neutral (Black) carrying single phase supply from secondary transformer and utility pole (3 Phase, 4 Wire (Star) System) to the single phase energy meter.

Both the Live and Neutral wires go to the Main Double Pole Circuit breaker. The Live from DP MCB then connected to the common busbar segment for MCBS which is directly connected to the Single Pole Circuit breaker. The outgoing of the SP MCBS are connected to the sub circuits, final sub circuits and electrical devices and appliances then.

The Neutral from the Main DP MCB is connected to the Neutral Link and the outgoings wires are connected to the sub, final sub circuits and electrical appliances. Keep in mind all the electrical appliances and appliances should be connected to the Earth Link for safety which is directly connected to the earth electrode and earth plate for proper earthing and grounding.

While we have already discussed the distribution board, types of distribution boards such as Main Distribution Board (MDB), Sub Distribution Board (SDB), Final Distribution Board (FDB), Sub Circuits and Final Sub Circuits in the previous post, Therefore, We will only discus the main electrical wiring accessories used in this basic Single Phase Home Supply Main Distribution Board Installation.
